Multiple stages of reactors form a bio-reforming reactor that generates chemical grade bio-syngas for any of 1) a methanol synthesis reactor, 2) a Methanol-to-Gasoline reactor train, 3) a high temperature Fischer-Tropsch reactor train, and 4) any combination of these three that use the chemical grade bio-syngas derived from biomass fed into the bio-reforming reactor. A tubular chemical reactor of a second stage has inputs configured to receive chemical feedstock from at least two sources, i) the raw syngas from the reactor output of the first stage via a cyclone, and ii) purge gas containing renewable carbon-based gases that are recycled back via a recycle loop as a chemical feedstock from any of 1) the downstream methanol-synthesis-reactor train, 2) the downstream methanol-to-gasoline reactor train, or 3) purge gas from both trains. The plant produces fuel products with solely 100% biogenic carbon content as well as fuel products with 50-100% biogenic carbon content.

Multi-purpose application of the second stage of a 2-stage bio-reforming reactor system for reforming bio-syngas, natural gas and process recycle streams

A bio-reforming reactor receives biomass to generate chemical grade syngas for a coupled downstream train of a low-temperature Fischer-Tropsch reactor train that uses this syngas derived from the biomass in the bio-reforming reactor. A renewable carbon content of the produced gasoline, jet fuel, and/or diesel derived from the coupled downstream train the low-temperature Fischer-Tropsch reactor train are optimized for recovery of renewable carbon content to produce fuel products with 100% biogenic carbon content and/or fuel products with 50-100% biogenic carbon content. The low-temperature Fischer-Tropsch reactor train produces syncrude, transportation fuels such as bio-gasoline or bio-diesel, or a combination thereof.

A bio-reforming reactor receives biomass to generate chemical grade syngas for a coupled downstream train of any of 1) a methanol-synthesis-reactor train, 2) a methanol-to-gasoline reactor train, and 3) a high-temperature Fischer-Tropsch reactor train, that use this syngas derived from the biomass in the bio-reforming reactor. A renewable carbon content of the produced gasoline, jet fuel, and/or diesel derived from the coupled downstream trains of any of 1) the methanol-synthesis-reactor train, 2) the methanol-to-gasoline reactor train, or 3) the high-temperature Fischer-Tropsch reactor train are optimized for recovery of renewable carbon content to produce fuel products with 100% biogenic carbon content and/or fuel products with 50-100% biogenic carbon content. A carbon-dioxide gas feedback loop cooperates with a CO2 separation unit to supply a fraction of the CO2 gas that is removed from the chemical grade syngas produced from the reactor output of the BRR to supply extracted CO2 gas to the biomass feed system.
